I looked for the answer to this question in the forum but could not find it, so I opened this article.
I successfully installed the Opengd77 firmware on my DM1701 radio and made all zone and channel settings in CPS correctly. Additionally, I successfully loaded the file I downloaded from Pistar onto the Raspberry SD card. I aim to make the device a long distance mmdvm hotspot. And with the settings I made, I can now successfully install mmdvm in hotspot mode. I can both send and receive. My problem is that although I wrote the latitude and longitude information of the hotspot I created on both the http://pi-star/admin/ configuration page and the brandmeister.network page, my hot spot does not appear on the aprs.fi page. can you help me with this?

AFIK aprs.fi is a completely different service to Brandmiester.

The hotspot does not receive APRS signals on FM or DMR and send then to aprs.fi, so I can't see why it should appear on the aprs.fi map.

The firmware can't receive APRS FM signals, or operate in FM mode with PiStar

In DMR mode the hotspot will pass the In-Call GPS data, which it receives as part of a normal DMR audio transmission, but the network Brandmeister handles forwarding the In-Call GPS to aprs aggregation servers.

Thank you for your answer. I understand what you say, but I do not want the radios to send daprs signals via hotspot. Aprs.fi also shows the location coordinates of hotspots made with mmdvm cards purchased from Chinese sites. Can't we see this hotspot we created with opengd77 on the aprs.fi map?

That hotspot location needs to be defined in the MMDVMHost configuration (see [Info] section).

If I used MMDVMHost standalone (on a Linux host without pi-star) I noticed that aprs.fi wasn't update so it's probably some other component in pi-star
that reports to aprs.fi , probably APRSGateway.

But check that you enabled it in pi-star:

Yes, few years ago all the APRS connection has been moved to the dedicated APRSGateway software.
Of course, in its configuration, you also need to enter your own Ham "password" to connect aprs.fi (I think there is an editor in the Expert "tab" fro the APRSGateway).

You can also take a look at the APRSGateway log (located in /var/log/pi-star/) to check if the connection is successul or not.

I haven't entered any aprs password for my HAT hotspots, but I can try running a pi-star only connected to a OpenGD77 radio to see what happens.
I think it should work out of the box.
